The mobile phone signal shield in the examination room has become a tool for the examination room to escort the information security of the examination room. However, if we do not use the equipment correctly, there will be poor results, even in the event of an examination room accident. The National Bureau of education has long selected Bochuang space-time brand mobile phone signal shield for the construction of standardized examination rooms.

Correct use of mobile phone signal shield in the examination room:

1. The effective shielding range of the examination room signal shield will be different in different use sites. This is closely related to the signal field strength on site. For mobile phones of different systems, the shielding range at the same site is not necessarily the same (search for the signal strength of Bochuang spatiotemporal shield). You can query the use environment signal strength, and the Bochuang spatiotemporal shield machine can be selected according to different signal strength;

2. The factors affecting the shielding range include but are not limited to: distance from the base station, orientation, presence or absence of obstacles, wall material of on-site buildings, installation height of the shield, installation specifications, etc;

3. Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one by one. Before starting the shield, ensure that each antenna is connected reliably. It is not allowed to start the machine without the antenna. There are many built-in shields in the school examination room. The built-in shield integrates the power supply. The antenna does not need to be installed in the machine shell for plug and play, which is convenient and fast;

4. After working for a long time, the surface temperature of Bochuang space-time shield is about 40 ~ 50 ℃, which is normal. If the surface temperature is too high, please turn off the power and try to contact your local dealer or agent;

5. The normal installation height is 1.8m ~ 2.5m. Try to install it in a position without obstacles between the target shielding area and the target shielding area. The wall mounted installation requires the antenna to be vertically upward. When the desktop is placed and used, the antenna can be vertically upward after breaking 90 degrees. There can be no AC power line or other audio and video lines within 0.2m around the antenna. The built-in mobile phone signal shield belongs to the directional shield, which can be installed in the middle of the two sides close to the wall. The space is large, and the shield can be more superimposed and covered for better effect.

Mobile phone signal shields are often used in school examination rooms, student dormitories, church meeting rooms, factory workshops, toilets, anti drug centers, prisons, troops and other places.

In order to prevent students from using mobile phones to transmit information, divulge test papers, test fraud and other purposes, some school tests are also to prevent teachers from divulging test paper information on the way of escorting test papers, which will have a negative impact on future tests. Is the mobile phone signal shield suitable for installation in all school examination rooms? According to the different signal strength of mobile phone signal shields installed in school 

examination rooms across the country, Bochuang space-time brand shields R & D and production of all kinds of mobile phone signal shields, mobile Unicom Telecom three networks 2g.3g.4g.5g mobile phone signal shields, wireless network Bluetooth signal shields 2.4g.5.2g.5.8g full coverage, effectively preventing students from cheating in the examination room and ensuring the fairness of the examination.
